TWISTER TRAVELER.

Application filed July 21, 1926. Serial No. 123,872.

This invention relates to self-lubricating twisting travelers, and involves certaln changes in the construction of the travelers shown inv my prior Patent No. 1,415,072 granted May 9, 1922, to which reference is made as containing a full discussion of the problem involved in this art,

According to my present invention, the lubricant collecting area of the traveler formed as a pocket or recess pressed out of the ring-contacting face of the traveler. Th s pocket or recess acts as a trap for the lubrleating grease with which the twisting. ring is smeared. During the run of the spindle, the contact of the traveler with the ring me chanically transfers particles of such grease to the traveler, and as the traveler becomes heated, the lubricant thus transferred to it melts andfiows out of said pocket towards the traveler foot where the wear is greatest and the need of proper lubrication most essential. i

In the accompanying drawings I have shown'a form of twister traveler which well illustrates the principles involved. In thesc drawings Fig. 1 is an elevation of a traveler, in ac-' between its ends, is pressedout to provide a ring and mechanically transfers to itself particles of the lubricating grease, and these particles are caught or collected in the pocket or recess 3 pressed out of the body of the traveler itself. I

i Thelubri'cant thus transferred to the traveler melts under the heat developed between the traveler and the ring in the operationv of the traveler and flows downwardly toward the traveler foot 4' where the need for adequate lubrication is most pronounced. 7

By pressing or indenting the pocket from the metal of the traveler, I avoid the physical removal of any metal, with resultant variation in weight of the traveler, as well as permittingconvenient production of the travelers in commercial quantities.

Various other modifications in structure and arrangement as come within thespirit of my invention may obviously be made within the limits of the appended claim.

WhatI therefore claim and desire to secure by Letters Patent is:

A twister traveler for use on avertical twisting ring comprising a member presenting a top flange, a bottom foot, and a back connecting said flange and foot, said back he ing pressed out to provide a lubricant pocket terminating short of the traveler foot.

In testunony whereof I aflix my signature.

I PHILIP C. VVENTWORTH.
